Abstract: Abstract of the Disclosure A roof paver system includes a plurality of roof paver elements having alternating dovetail-shaped and tapered grooves and an upper surface having raised por-tions to generate vortices for preventing wind from lifting the elements and to provide a safety tread. Connector members are provided in some of the dovetail grooves to interconnect the roof paver elements to fur-ther prevent their displacement.  The tapered grooves break the vacuum between the roof paver elements and the molds in which they are formed.  Some of the dovetail grooves are composite grooves defined by the cooperation of adjacent roof paver elements.  Clips are provided to mate with outwardly projecting toes on the roof paver elements in perimeter courses to align and anchor them, and elongate battens, which are dovetail-shaped in cross section, are received in the dovetail grooves and include openings for receiving thin elements transverse to the battens to engage the concrete elements at the ends of the grooves.      In one embodiment, the connector members have a truncated triangular cross section to provide a sub-stantial area of contact with the walls of the dovetail grooves and ridges to bind against the walls.  Flange stops project from the connector members to engage the roof paver elements at the ends of the dovetail grooves, and one end of the connector member has a bevel to mate with a roof paver element oriented with its grooves perpendicular to the connector member.

Patent CA-1328784-C (CA)
Inventor: DEBE MARK K
IPC: C23C14/12
Filed: 1987-07-17
Granted: 1994-04-26
Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to microstructured surfaces.          Microstructured surfaces currently in use and the processes used to make them have one or more shortcomings. Some have wide variation in the size distribution or aspect ratio of the microstructure.  This variation renders the properties of the microstructured surface difficult to specify, making the surface a poor candidate for optical uses such as absorption or reflectivity.  Some microstructures are peculiar to specific substrates, many of which are subject to corrosion.  Some microstructured surfaces are opaque to electromagnetic radiation.  This limitation precludes their use with transparent media.          This invention provides an article comprising a substrate bearing a microlayer which comprises uniformly oriented, crystalline, solid, organic microstructures and a method for preparing said article.  The microstructures may be mono- or polycrystalline.  In the preferred embodiment, the microstructures are of uniform shape and size.          The articles can be prepared by (1) depositing a vapor of an organic compound as a thin, continuous film onto a substrate to provide a composite, and (2) annealing the composite in a vacuum sufficiently such that a physical change is induced in the orginal deposited film to form the microstructures.          The microlayer can be overcoated with other materials to provide desired properties to the article. The articles of this invention are useful for many forms of light trapping, energy absorption, imaging, data transmission and storage, and gradient index applications.

Abstract: ABSTRACT OF THE DISCLOSURE     A fibrous sheet useful as a battery plate separator is disclosed. The sheet, in a specific embodiment, is made from a mixture of Grade 210 glass fibers, Grade 206 glass fibers, Grade A-20 chopped glass strand, and Grade A-121 polyethylene fibers. The fine glass fibers impart a high absorbency to the sheet;  the coarse glass fibers impart a lower absorbency;  and the polyethylene fibers, which are hydrophobic, are essentially non-absorbent.  The different fibers are used in such proportion that the sheet has the absorbency, usually from 75 to 95 percent, required for use in a recombinant battery, even in the presence of free electrolyte.   A recombinant battery in which fibrous sheets as described above serve as plate separators is also disclosed, as a method for producing a recombinant battery which includes the steps of assembling a plurality of electrodes with such sheet separators in a case, flooding the electrodes in the case with an electrolyte, removing electrolyte that is not absorbed by the sheet separators from the case, and closing the case.   Finally, a recombinant battery in a case which has an opening is also disclosed; the opening is closed by a thin film of polyethylene or the like through which hydrogen can escape at a faster rate than oxygen.

Abstract: METHOD AND APPARATUS FOR INTERMITTENTLY PROCESSING SUCCESSIVE DEFINITE LENGTHS OF A CONTINUOUS FLEXIBLE WEB               Abstract of the Disclosure A system is provided for intermittently processing succes-sive definite lengths of flexible sheet material in continuous web form, e.g., tractor-fed computer printout paper, with nearly tensionless transport of the web through web feeding operations, cyclical web processing and driving operations, and web delivery operations, that are not speed-interdependent.  For each processing cycle, with the web extended without slack through an upstream lead to a processing station where a certain length of the web is positioned to be nest processed, an excess length of loose web is fed into that lead, typically forming a loop in it; then the certain web length is processed and driven forward a distance shorter than the length of loose web; and then web is retracted from the upstream lead to remove the residual loose web and leave a next certain web length in position to be processed. The processed web is delivered and may be folded into a pack as a downstream lead of it is made slack by web driven from the processing station.  The system enables increased speeds of offset printing of paper such as continuous computer printout forms.
